摘　　要：针对渤海QHD32 6油田钻井中钻屑形成泥球的突出问题 ,依据钻屑形成泥球的原因分析 ,采用粘结法、全角滚动法等实验方法 ,评价了自己研制的“FNJ 1”型防粘结剂的抑制钻屑粘结作用效果 ,并应用该剂于渤海QHD32 6油田上百口井的钻井试验中 ,取得抑制钻屑形成泥球的显著效果。Aimed at the outstanding problem that drilling cuttings form mud balls during drilling operation in Bohai oilfield and based on analyzing the reason of formation of mud balls, a new type of anti?binding agent FNJ?1 has been developed. Results show that remarkable success has been gained in inhibiting drilling cuttings bonding when using FNJ?1 in several hundred wells of Bohai QHD32?6 oilfield.
